UPSLOPE FLOW AND LIFT AHEAD OF UPPER LEVEL TROUGH MOVING EAST ACROSS THE FOUR CORNERS REGION HAS GENERATED SHOWERS/THUNDERSTORMS OVER THE SERRANIAS DEL BURRO OF MEXICO. HI-RES MODELS BRING SOME OF THESE EAST TO NEAR I-35 BY MIDNIGHT PRIOR TO DISSIPATION. THE HI-RES MODELS HAVE DONE WELL LATELY AND WILL FOLLOW THEM.

THE UPPER LEVEL TROUGH MOVES OUT INTO THE PLAINS STATES THURSDAY DRAGGING A PACIFIC FRONT EAST TO ALONG AND EAST OF I-35 BY AFTERNOON.

THIS WILL DRAG ANOTHER PACIFIC FRONT ACROSS SOUTH CENTRAL TEXAS TO NEAR THE I-35 SUNDAY AND TO THE COAST MONDAY. MOISTURE CONVERGENCE ALONG THE FRONT WILL GENERATE ISOLATED SHOWERS AND THUNDERSTORMS ACROSS EASTERN AREAS SUNDAY AND FAR EASTERN AREAS MONDAY MORNING WITH SOME STRONG STORMS AGAIN POSSIBLE. A WARMING TREND IS EXPECTED FRIDAY THROUGH MONDAY...ESPECIALLY SUNDAY INTO MONDAY DUE TO DOWNSLOPE EFFECTS AND WARM TEMPERATURES OFF THE MEXICAN PLATEAU. A COLD FRONT WITH SOME ORIGINS IN CANADA WILL SURGE ACROSS SOUTH CENTRAL TEXAS TUESDAY WITH A COOLER AIRMASS AND BELOW AVERAGE TEMPERATURES BY WEDNESDAY. FIRE WEATHER... ELEVATED FIRE WEATHER CONDITIONS ARE EXPECTED DUE TO LOW HUMIDITIES AND NORTHWEST WINDS AROUND 10 MPH ALONG THE RIO GRANDE INTO THE EDWARDS PLATEAU THURSDAY AFTERNOON.
